X-ray free-electron lasers provide femtosecond-duration pulses of hard X-rays with a peak
brightness approximately one billion times greater than is available at synchrotron radiation …

X-ray photon correlation spectroscopy (XPCS) enables the study of sample dynamics
between micrometer and atomic length scales. As a coherent scattering technique, it …

Photosystem II (PSII) is a huge membrane-protein complex consisting of 20 different
subunits with a total molecular mass of 350 kDa for a monomer. It catalyses light-driven …

By illuminating matter with bright and intense light, researchers gain insights into material
composition and properties. In the regime of extremely short wavelengths, X-ray free …

Inorganic–organic hybrid materials represent a large share of newly reported structures,
owing to their simple synthetic routes and customizable properties. This proliferation has led …

Bacteriorhodopsin (bR) is a light-driven proton pump and a model membrane transport
protein. We used time-resolved serial femtosecond crystallography at an x-ray free electron …

Photolyases, a ubiquitous class of flavoproteins, use blue light to repair DNA photolesions.
In this work, we determined the structural mechanism of the photolyase-catalyzed repair of a …

Serial femtosecond X-ray crystallography (SFX) has revolutionized atomic-resolution
structural investigation by expanding applicability to micrometer-sized protein crystals, even …

Since the invention of the first lasers in the visible-light region, research has aimed to
produce short-wavelength lasers that generate coherent X-rays,; the shorter the wavelength …

Chromophore cis/trans photoisomerization is a fundamental process in chemistry and in the
activation of many photosensitive proteins. A major task is understanding the effect of the …
